> Some systems may wish to send 32- or 64-bit decimal values on the wire without any conversions. Computations engines using Arrow may choose to promote these to 128-bit right away on receipt, but it would be useful to be enable systems with native handling of the smaller-size types to be able to send data via Arrow streams / IPC without extra serialization
